Delphi DLL Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.CrcBytes method

Shows how to replace the deprecated CrcBytes method. (Chilkat is moving away from the use of CkByteData.) Delphi DLL

var
crypt: HCkCrypt2;
path: PWideChar;
algorithm: PWideChar;
inData: HCkByteData;
crc: Cardinal;
bdIn: HCkBinData;

begin
crypt := CkCrypt2_Create();

path := 'c:/someDir/example.dat';
algorithm := 'crc-32';

//  ------------------------------------------------------------------------
//  The CrcBytes method is deprecated:

inData := CkByteData_Create();
CkByteData_loadFile(inData,path);

crc := CkCrypt2_CrcBytes(crypt,algorithm,inData);

//  ------------------------------------------------------------------------
//  Workaround.
//  (Chilkat is moving away from using CkByteData)

bdIn := CkBinData_Create();
CkBinData_LoadFile(bdIn,path);

crc := CkCrypt2_CrcBd(crypt,algorithm,bdIn);

CkCrypt2_Dispose(crypt);
CkByteData_Dispose(inData);
CkBinData_Dispose(bdIn);
